Abstract

This paper examines the impact of the high-speed railway (HSR) on collaborative innovation in China, with a focus on university-industry collaboration (UIC). The data pertain to a universe of patent applications filed by all universities and colleges in China and their forward citations during the 1985-2016 period. Taking advantage of HSR collection as a quasi-natural experiment, we seek to estimate the causal effect of HSR on collaborative innovation measured by patents applications filed by multiple assignees and the corresponding forward citations. A variant of differences-in-difference (DID) model is employed, using both city-level and paired applicant-level datasets. We find that HSR could significantly lead to patent collaboration across cities. This induced effect becomes effective for incremental innovation captured by utility patent in a short period but takes several years for radical innovation embodied in invention patents. Moreover, three mechanisms are further explored to reveal the role of universities’ specialized academic fields, geographical distance, and technology proximity on the HSR-induced collaborative patent innovation between university and firm.
